' ACCELERATOR To all whom it may concern r Be it known that I, ToRvALJ. ANDERSON,

a citizen ofv the United States, residing at vide a device of the kind stated which can be readily installed on the car, and which is simple in construction and reliable in operation.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing, in which:

Figure 1 is an elevation of the complete device installed; Fig. 2 is an enlarged plan view of the device minus a foot pedal, and Fig. 3 is an elevation of the foot pedal.

Referring specifically to the drawing, 5 denotes the throttle lever of a carbureter 6, the outlet end of the latter being connected to the usual intake manifold 7 The connected ends of the carbureter and the intake manifold are flanged, and by means of bolts 8 passing through these flanges the connection is made.

One of the bolts 8 serves to support a bracket member 9 by means of an arm 9 extending from said member and clamped to the back of the manifold flange by being seated beneath the head Flanges 9 are formed on the member 9, and engage the edges of the flange of themanifold, to prevent the bracket member from becoming disarranged. To the bracket member 9 is pivoted as shown at 10, an angle lever having connected to one of its branches 11 an actuator rod 12, and to its other branch 13 a spring 14 anchored to the bracket member, said spring serving to swing the lever in a direction opposite to that it is adapted to be swung by the rod 12.

To the outer end of the lever branch 13 is connected one end of a link 15 having its other end provided with a curved'slot 16,

of said bolt.

and intermediate its end, the link 15 is an nected to the throttle lever 5, as shown at 16 The connectionbetween the link 15 and the lever branch 13 lS'SllOWIl at 17. It will be understoodofcourse, that the connections 16 fiand 17 are pivoted connections. p At 18 is shown theusual cross rodwhich isordinarily connected to the throttle level 5, and forms a part of the hand throttle control mechanism. This rod instead of be ing directly connected to the throttle lever 5, is connected to-the-link' 15, it being provided with a downturned end which seats loosely in theslot 16. The rod 18crosses and rests on rod12so that it may work freely in slot 16 andnot stick or wedge therein.

The throttle lever 5 is operated to open the throttle by pushing the rod 12 in the di-, rection of the arrow in Fig. 2. This move ment of the rod 12, swings the lever arm 13 in such a direction that, through the link 15, the lever 5 is swung to throttle-opening position. The rod 18 does not interfere with this operation, due to its sliding connection with the link 15. The throttle can also be opened by pulling the rod 18 in the direction of the arrow in Fig. 2, whereupon the link 15 swings the throttle lever 5 as before. The spring 14 operates in both instances to retract and restore the parts to their normal position.

The rod 12 is operated by a foot pedal 19, pivoted as shown at 20, to a support 21 mounted on the foot board 22 of the car, the latter being apertured for the passage of the rod to the forward end of the foot pedal to which it is pivotally connected as shown at 23. The rear end of the support 21 carries a back stop 24 for the foot pedal 19 to permit the use of the latter as a foot rest. The pivot runs through a bushing 20.

The foot pedal end of the rod 12 is a tubular section 12 which telescopically seats a stem 12 by which the connection 23 with the foot pedal is made. A suitable clamping means 2 1 locks the parts 12 to 12 together. The purpose of this structure is to permit lengthening and shortening of the rod 12 for the proper adjustment of the device.

The part 12 carries an adjustable abutment 25 to limit the travel of the rod 12, in the direction to close the throttle, by engagin the foot board 22.

he foot pedal 19 may also have a rubber facing to prevent slipping of the foot.

The closing movement of the throttle valve is not dependent entirely on the spring 14, because it the latter should break, or any parts of the accelerator mechanism stick, the throttle valve can be opened or closed by the rod 12 actuated by foot pedal 19. Referring to Fig. 2, it will be noted that the slotted end of the link 15 projects, and hence it can be grasped and operated manually to open and close the throttle valve. This facilitates adjustment of the carbureter, as the link 15 is close to the oarbureter needle valve or other parts to be adjusted, and the throttle valve can be opened, and closed, without the operator leaving the oarbureter and operating the foot pedal or the throttle lever on the steering Wheel.

The accelerator is designed more particularly for a Ford automobile, and it can readily be installed without extra bolts and without any changes in the carbureter, and the hand throttle lever on the steering wheel can be set in any position Without danger of the throttle valve being forced to closed position by the spring 1a, the latter, as pointed out hereinbefore not being depended upon altogether for closing the throttle valve. The spring may be a very Weak one as the throttle valve can be opened and closed by the pedal 19.

I claim:

The combination With a carbureter throttle lever, of an angle lever, a link connected at one end to one branch of the angle lever, an actuator rod connected to the other branch of the lever, a connection between the link and the throttle lever intermediate the ends of the link, said link having a longitudinal slot in its end Which is opposite the first mentioned end, and an actuator rod having a sliding connection with the slotted end of the link, said rod extending across and resting on the first-mentioned actuator rod.

In testimony whereof I afiix my signa- 'ture.

TORVAL J. ANDERSON.
